We look at the division of 72245128 by 210 
We want to divide 72245128 by 210.

Step 1:
When dividing 7 by 210, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 210

Let's proceed to step 2:
If we divide 72 by 210, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 210

Going ahead to step 3:
722 divided by 210 is 3 with a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 630 from 722 leaves us with 92.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 210

Advancing to step 4:
If we divide 924 by 210, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 840 from 924, we get 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 210

Step 5:
When dividing 845 by 210, we get 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 344.0
The remainder is 5 after subtracting 840 from 845.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 210

Advancing to step 6:
210 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 3440.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 210

Advancing to step 7:
If we divide 512 by 210, we get 2 and a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 34402.0
If we subtract 420 from 512, we get 92.
Append the next digit (8) from the dividend to 92 and continue with: 928 / 210

Step 8:
The number 210 fits into 928 4 times, leaving a remainder of 88.
The next digit of our result is 4. 
Result so far: 344024.0
Subtracting 840 from 928 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
210 goes into 880 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 344024.4
The remainder is 40 after subtracting 840 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
210 goes into 400 1 times with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 344024.41
If we take 210 away from 400, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
The number 210 fits into 1900 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 344024.419
Subtract 1890 from 1900 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 210, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 344024.419
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
If we divide 1000 by 210, we get 4 and a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 344024.41904
The remainder is 160 after subtracting 840 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
The number 210 fits into 1600 7 times, leaving a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 344024.419047
Subtracting 1470 from 1600 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 15:
210 can be fit into 1300 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 344024.4190476
Subtract 1260 from 1300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
The number 210 fits into 400 1 times, leaving a remainder of 190.
The next digit of our result is 1. 
Result so far: 344024.41904761
Subtract 210 from 400 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 344024.41904761 with a balance of 1.9e-07.
